Five persons from 2 families residing at Miyama Town, Mie Prefecture, Japan, ingested fresh raw fish Oncorhynchus sp. on 9 May 1999 that was caught at Owase district in Mie. They all expelled diphyllobothriid cestodes 11-37 days after ingesting the fish. The parasites were morphologically identical to Diphyllobothrium nihonkaiense Yamane et al., 1986. Five plerocercoids were detected from a portion of the fish. Nucleotide sequence of a region of the cytochrome c oxidase subunit I gene of mitochondrial DNA from an adult worm was identical with that from the plerocercoid. The fish was identified as Oncorhynchus masou ishikawae according to the nucleotide sequence of the nuclear ribosomal second internal transcribed spacer region II gene. This is the first record of D. nihonkaiense plerocercoids from O. m. ishikawae.
1999年5月9日，居住在日本三重县志摩市宫山镇的2个家庭中的5人食用了在三重县尾鹫地区捕获的新鲜生鱼虹鳟属鱼类。他们在食用该鱼11至37天后均排出了阔节裂头绦虫。这些寄生虫在形态上与1986年山根等人发现的日本阔节裂头绦虫相同。从部分鱼肉中检测到5个裂头蚴。成虫线粒体细胞色素c氧化酶亚基I基因区域的核苷酸序列与裂头蚴的相同。根据核糖体第二内部转录间隔区II基因的核苷酸序列，该鱼被鉴定为石川哲罗鱼。这是首次从石川哲罗鱼中发现日本阔节裂头绦虫裂头蚴的记录。
